Resonant laser ionization of polonium at RILIS-ISOLDE for the study of ground- and isomer-state properties

[摘要] Three new ionization schemes for polonium have been tested with the resonant ionization laser ion source (RILIS) during the on-line production of Po-196 in a UCx target at ISOLDE. The saturation of the atomic transitions has been observed and the yields of the isotope chain Po-193-198,Po-200.202,Po-204 have been measured. This development provides the necessary groundwork for performing in-source resonant ionization spectroscopy on the neutron-deficient polonium isotopes (Z = 84). (C) 2008 Elsevier B.V.
